Actually Phil has a point. If you are after the characteristics of a triode, a   
   depletion mode JFET is practically identical except that it can conduct in   
   reverse. If you don't intend to use a transformer that trait means nothing.    
      
   If you really want to emulate tube sound you might consider building a   
   micropower output with tubes and actually feed a speaker. You could even build   
   a box for the speakers and mike, a properly placed baffle with properly placed   
   vents and a properly    
   placed mike would be about as close as it gets. Set the B+ low enough so it   
   actually clips the output stage and you should be good to go, and I don't see   
   many of that type of devices out there, but I don't look either. I did work in   
   the field for a time    
   and I think I would have noticed.
